ELASTIC OR PLASTIC COMPOSITION.

SPECIFICATION forming part of Letters Patent No. 525,086, dated August 28, 1894.

Application filed larch 1B, 1894. Serial No. 503,780. (No specimens.)

To all whom it may concern.-

Be it known that I, J OSEF PATTIGLER, a subject of the Emperor of Austria-Hungary, residing at Vienna, Austria-Hungary, have in- 5 vented certain new and useful Improvements in Elastic or Plastic Compositions, of which the following is a specification.

My invention relates to the manufacture of a compound having somewhat the properties and applications of india rubber or analogous substitutes and adapted for various technical purposes in the arts.

The principal object of my invention is to provide a simple, inexpensive, durable and efiicient compound partaking somewhat of the nature of india rubber.

My invention consists of a composition con sisting of the ingredients compounded in substantially the manner hereinafter described and claimed.

The nature, objects and general scope of my invention will be more fully understood from the following description, pointing out one preferred method of compounding the article, which in practice has been found efficient.

A charge of linseed oil is placed in preferably a steam eate ettle or the like and boiled until bubbles thereof are formed therein, when there is added successively thereto five parts of white zinc, two parts of soluble lass, which is silicate of otash and soda, w1t the alkali predominating, one-fifth part of minium gred lead) and one and one-half to two par as es as in powdered or other form. These materials are added separately to the oil while the latter is in astate of ebullition. It may, however, be here remarked that the above ingredients as to quantity may be varied at pleasure and equally good results he obtained. Moreover, that during the introduction of each to the oil, the same should be thoroughly stirred or agitated, in order to permit of an intimate admixture or combination thereof with the oil, before adding the other materials hereinafter mentioned to the mass.

After the thorough admixture of the several materials to the more or less liquid mass caout- 5o chouc or the like with acne half (a) part of enzine is added thereto,in order to produce 7 (o v a resultant thick or consistent composition. If the mass should be found to be too thick, the same may be thinned by the addition of a pre scribed quantity of linseed oil, g ycerine, ar-

aifiu or other ve etable or minera Oll an during the introduction of the same, the combined mass should be thoroughly stirred and at the same time heated to insure a more perfect mixture thereof. To the compound in 60. some cases is then added suitable colorin matter and after thorough admixture therewith, the same may be poured into a mold or under pressure caused to assume the desired form in a mold, for subsequent use when withdrawn therefrom.

It may be here remarked that the above named compound is especially adapted for molding casts, terra cotta and stucco work, busts and for other technical purposes; and moreover, that the same is water-proof and non-inflammable, and while readily carbonizing yet in the presence of an intense heat or flame such will have no effect upon the same.

It will be manifestly obvious to those skilled in the art to which my invention appertains that the proportion of the respective ingredients entering into the manufacture of the compound hereinbefore described may be varied withoutdeparting from the spirit of my invention, and hence I do not wish to be understood as limiting myself to the precise proportions mentioned.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Acomposition, consisting of an oil, caoutchonc, zinc-white, soluble glass, minium and asbestos, substantially as and for the purpose set forth.

2. A composition, consisting of vegetable or mineral oil, caoutchouc, 'zinc-white, soluble glass, minium, asbestos and coloring matter, substantially asand for the purposes set forth.

In witness whereof I hereunto set my hand 5 in presence of two witnesses.
